The 70% Rule Explained: How to Calculate Maximum Purchase Price
The 70% rule is the most widely used formula in fix-and-flip investing. Learn how it works, when to use it, and when to break it.
Multifamily flips offer larger profit potential but different analysis requirements. Here's how to evaluate them.
Multifamily properties (2–4 units, or small apartment buildings) offer fix-and-flip investors several advantages: larger total profit per project, multiple units to spread risk, and a broader buyer pool that includes both owner-occupants and investors. The analysis, however, requires additional considerations.
Valuation for small multifamily (2–4 units) uses the same comparable sales approach as single-family, but comps are scarcer and more variable. Supplement your comp analysis with an income approach: calculate the property's Net Operating Income (gross rent minus operating expenses) and apply the local cap rate to estimate value. Both approaches should produce similar results — if they diverge significantly, investigate why.
Renovation planning must account for occupied units. If tenants are in place, you may need to renovate unit by unit, providing temporary relocation for each tenant during their unit's renovation. This extends your timeline and requires more complex scheduling. Alternatively, if the property is vacant, you can renovate all units simultaneously for a faster turnaround.
Financing for multifamily flips may differ from single-family. Some hard money lenders specialize in residential properties (1–4 units) while others prefer commercial (5+ units). Loan terms, LTV ratios, and rates may vary. Explore your options before committing to a deal.
Exit strategy flexibility is a major advantage. You can sell to an investor (valuation based on income and cap rate), sell to an owner-occupant (one unit to live in, rental income from others), convert to condos (if local regulations allow, potentially increasing total value), or hold as a rental (strong cash flow from multiple units).
The per-unit renovation budget is typically lower than single-family because rental units don't need the same level of finish as a home being sold to an owner-occupant. Focus on durable, easy-to-maintain materials that look good but withstand tenant use.
